I've a problem in my printings. The top and bottom infill are not perfect (see image) compared with the "skirt" part.

Any thoughts? Speeds? Infill %?

Best Regards

Im having the same problem. Switching to Cura has seemed to help.

I've had better luck following Nophead's advice and printing at a constant speed where possible. This gives a more consistent flow rate out of the nozzle, by keeping the "plug" size constant where the plastic is transitioning from solid to melted. I've got everything except for rapid movements and bridging set to around 30mm/sec and all my prints have been looking great.

There are probably other ways but this has worked for me.

Just a small remark, it's a 'brim' and not a skirt winking smiley

Skirt is the line that goes around the print, but that does not touch the print, it is meant for your hotend to build up pressure inside.

You need to calibrate E steps. Follow this excellent guide to have it super calibrated. [reprap.org]
Brim is not a good for comparison because its a first layer and they tend to be thicker depending on your nozzle height.
